Alpha/Beta Quadrant Overview
Sector 70 (aka Qo'noS Sector) was a region of space in the Beta Quadrant. This sector was in sector block Omega Leonis. In this sector, Qo'noS, the Klingon homeworld and capital of their empire, was located in the Qo'noS star system. (Star Trek Into Darkness; DIS: "Context Is for Kings")
In the alternate reality, the Qo'noS system was close to the edge of the Neutral Zone.
In 2259, activity within this zone was being monitored by Starfleet. Results from this intelligence gathering were displayed on a galactic map, with its focus primarily on the Alpha Quadrant, which was in a collection of graphics and video media that were seen on a powerwall in the offices of Admirals Christopher Pike and Alexander Marcus at Starfleet Headquarters.
In late February of 2259, Khan Noonien Singh used a portable transwarp beaming device to flee from his attack on Starfleet Headquarters in San Francisco with a long-range site-to-site transport all the way from the stolen jumpship 208 on Earth to Ketha Province on Qo'noS. (Star Trek Into Darkness)
